New mod released for the Sega Master System model 2. The FM Sound Module Adapter.

The Japanese Sega Master System is capable of playing back both the PSG (Programmable Sound Generator) and FM (Frequency Modulation) audio that is programmed into some games because the consoles contains both the SN76489 PSG chip and the YM2413 FM chip. US and European consoles only contain the PSG chip which means they can not play back the FM audio.
